IMPROVEMENT lN' BENCH-PLANES.

Specification forming part of Letters Patent No. 209,246, dated October22, 1878; application filed August 29, 1878.

To all whom it may concern Be it known that I, PATRIGKGALLAGHER, ofEureka, in the county of Eureka and State of Nevada, have invented a newand Improved Bench-Plane, of which the following is a specification:

In the accompanying drawings, Figure 1 represents a verticallongitudinal section of my improved bench-plane, and Fig. 2 is a top Iview of the same with a part broken off.

Similar letters of reference indicate corresponding parts.

This invention has reference to improvements in bench-planes, so thatthe cuttingiron lies flat and will make a smoother cut in the wood,being also more easily adjusted than in the old styles of planes inwhich the iron is retained by a wedge-piece.

The invention consists of a bench-plane Whose cutter is firmly retainedby a clampscrew and a hinged and spring-acted cover on the slanting seatof the plane.

Referring to the drawings, A represents a bench-plane, either ajack-plane, fore-plane, or jointer, and made of wood or iron, of theusual size and shape. The iron cutter B is secured by a clamp-screw andslot to the slanting bot tom of the plane, which is laid flat thereon,so as to cut smoother. It is held firmly in position near thecutting-edge by a metallic cover or cap, 0, that is hung by ears (0 to acrosspln, b, the part above the pin being set at an ting its moreconvenient adjustment than when fastened by a wedge, as in the planes ingen eral use. The cutter may be turned over, if desired, so that thebevel of the cuttingedge will be either up or down, according to thegrain of the wood to be planed. For changing or removing the cutter theclamp-screw has to be unscrewed and placed in line with the slot, when,by pressing onthe upper part of the cover, the iron can be readily takenout. When replacing it the clamp-screw is tightened and the cutterthereby held rigidly in connection with the spring-cap.

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent- In a bench-plane, the combination of acutting-iron, screwed to the plane by a clampscrew, with a hinged cap orcover, and with springs attached to a detachable cross-piece or bridge,substantially" as and for the purpose specified.
